Mesh simplification using Quadric Error Metrics written in C#/.NET.
For more information about the algoritm check out the paper https://www.cs.cmu.edu/~./garland/Papers/quadrics.pdf
This program can be used to simplify a triangular mesh to target number of triangles or using quality multiplier, the relationship is as follows:
Quality * Input model tris count = Target tris count
Input mesh has to be in STL file format (.stl). Output mesh will also be in that format.
This is a dotnet global tool, for installation simply type in terminal:
dotnet tool install --global qem
You need to have .NET Core installed on your computer for this to work: https://dotnet.microsoft.com/download

This program is also included in nuget repository: https://www.nuget.org/packages/qem/
For offline installation the nuget package is also included as a release.
Compiled and tested using:
- Visual Studio 2019 v16
- .NET Framework v4.6.1
- Windows 10
In the terminal type:
qem <input file path> <output file path> -q <quality>
or
qem <input file path> <output file path> -t <target triangle count>
- input and output files should have .stl extension
- quality has to be between 0.0 and 1.0
- target tris count cannot exceed input model's tris count
If you do not specify neither quality nor target triangle count, the original model will be simplified by a quality factor of 0.5:
qem <input file path> <output file path>
